O ne of the disadvantages of DBMS is database systems require sophisticated hardware, software, and highly skilled personnel. It increased Redundancy and inconsistency. The principal advantages of DBMS over file processing system: • Flexibility: Because programs and data are independent, programs do not have to be modified when types of unrelated data are added to or deleted from the database, or when physical storage changes. … The fields in the record are separated using delimiters such as tabs and commas. Advantages of computer-based information systems→. In computer file-based processing system, the structure of data file is coupled with the individual application programs. Flat files are relatively quick and easy to set up and use. Difference Between Flat File & Relational Database, Convert an Acrobat PDF to Portrait or Landscape, Edgar F Codd's 13 Rules of Relational Databases - by Oracle DBA Online. Many software applications are created with flat file databases. of just one table. Each record within the table contains the same fields with the same type of information in each field, although of course the specific information you enter into each separate field is different. To summarise, flat flies are easy and quick to set up. These XML files are often used to build specific modules on a website, when the standard build follows a very specific pattern that is configured by a single value stored in an XML file, or a series of related values.

There are distinct advantages and also disadvantages to the flat file database. The patient database is an example of a flat-file as all of the information is stored in one single table: Key Words: One Table, Data Redundancy. We will call this an ‘adding anomaly’. Advantages of file-oriented system. Occasionally, the database may encounter errors that damage virtually all information within it. This is referred to as an ‘amendment anomaly’. Databases accessed on a network share are useful for access by many people who are looking for information. These are referred to as ‘adding, deleting and amendment anomalies’ and can result in the data in the records becoming inconsistent. A new operating system could be designed using a set of flat file databases. Ease of use: The revision of any information as tables consisting of rows and columns is much easier to understand .
